I would probably have to agree that the molecular clocks are suspect. There
is also evidence that even the mitochondria are under natural selection
which alters the rate of the clock.

OK, then how much change can one get if he changes 2 or 3 or 4... of the
homeotic genes? What is the limit to change? and why must we only allow one
of the homeotic genes to change? I don't think you will hold to a position
that only one can change, but there have been some recently who have said
that there is a limit to change and I see none.

If I have a set of 12 numbers:

382754302847

and I start mutating them one location at a time. What is the limit to
change? only the number of positions. In a dna genome there are the
equivalent of 3.5 billion numbers which can be changed by mutation. I see no
reason why there must be a limit to change in that sequence other than the
death of the organism or its failure to reproduce.
